I completely agree that instincts are natural and I have two cats. availability of food in the home does not deter animals from stalking and hunting other animals. It is part of the life cycle. I don't like seeing rabbits die, but I can't validate it just because they are cute. every animal on this planet is prey or predator. We have domesticated almost every type of living creature on this planet. Whether it is in personal homes, cages or zoos and reserves, we have domesticated animals and they still require the ability to live a "normal" lifestyle for them. smaller life species are extremely numerous and multiply more because of the quantity of species that prey on them. Anytime we have tried to prevent natural processes, we have tipped the balances in nature. Let the cats do what they do. It is instinctual whether they capture something cute or something we want to get rid of. Let them live life naturally.
